Combined the company said those things will increase fuel economy on its MP7 engine by 5.1% and on its MP8 engine by 5%. For its downspeeding tractor option Mack will offer the MP8 engine with a turbo compounding system that “converts waste energy from the exhaust to mechanical energy that is fed back to the engine.” The result is a fuel efficiency increase of 8.8% ° Volvo says it has retooled D11 engine offers a 2.2% fuel economy improvement over 2014 model.
